JOSEPH O. HUMBLE, OF RAOINE, YVISCONSIN.

TONGUELESS CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 309,057, dated December 9, 1884.

Application filed August 11, 1884. (N0 model.)

To all whom it may concern:

Be it known that I, J osnrn O. HUMBLE, of Racine, in the county of Racine, and in the State of YVisconsin, have invented certain new and useful Improvements in Tongueless Cultivators; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to tongueless cultivators, and will be fully described hereinafter.

In the drawings, Figure 1 is a side view of myiniproved cultivator. Fig. 2 is a transverse section taken through the axle of the same, and Fig. 3 is a section showing the means for suspending the axles from an upper connecting-bar.

The axle is made in two parts, A A, and in the form shown in Fig. 2. Each part has a vertical portion and two horizontal arms, a a.

On each arm a is slipped a sleeve, B, having a triangular flange, B, on its inner end, which latter is hollowed out to receive the vertical portion of one part of the axle A, in which position it is held against lateral play by a bar or plate, b, and a similar sleeve, 0, is in like manner secured to the upper arm, a, its outer end carrying the triangular flange. The sleeves O are reent'orced on the .top, and these rc-enforces have horizontal squared openings through them to receive a square connecting-bar, D, which is tightened in its adjacenoe by setscrews d d. Each of the triangular flanges of the sleeves B and O has lugs c c, that project from its basic corners, and these lugs are bored to receive the pivots c of rods E, that connect each adjacent pair of sleeves with each other. A plow is swiveled or otherwise attached to the rear of each sleeve B, and the upright portions of the axle A A form, with the bar D, an arch that spans the grain being cultivated, and this arch is sup ported not only by the upright portion of the axle, but by the rods E, which, while permitting the wheels to act independently, will prevent them from converging toward or approaching each other when the draft 011 one side is greater than that on the other, or when one wheel is in advance of the other, for, though the rods E will permit either wheel to advance beyond the other, the bar D will keep them apart. These rods also keep the triangular flanges in parallel lines and correct any tendency of the arch to fall either forward or back, and therefore the cultivator is always under control.

I propose to make the plow shown in Fig. l the subject of a separate application.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a cultivator, a twopart axle, each part consisting of an upright portion having at each end horizontal arms, in combination with rods E and sleeves B and O, as and for the purpose set forth.

2. The sleeves B B, having triangular flanges, in combination with the two-part axle and sleeves C and rods E, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of \Visconsin, in the presence of two witnesses.
